1998.5 Mercury Grand Marquis

Asking Price Range

Estimated MPG

Manufacturer's Suggested Retail Price (MSRP), also known as "sticker" price, is a recommended selling price that automakers give a new car that is above the invoice price paid by the dealer. It is a price that does not include any options that can be added to a particular car style. When shown as a range, the prices are starting MSRPs, without options, for multiple styles for that model.

This price range reflects for-sale prices on Cars.com for this particular make, model and year.

These city and highway gas mileage estimates are for the model's standard trim configurations. Where there are optional features, packages or equipment that result in higher gas mileage, those fuel-economy estimates are not included here.

The Beast

by Auto Turret from Detroit, MI | May 23, 2012

Have the LS Ultimate Edition with Precision Trac. Bought this car @ 140K, have now reached 200K with no issues other than wear and tear.. had to have a lot of front end suspension components replaced when first purchased, (tie rods, sway bar links, ball joints) as with any car driven in Michigan! Other than that, have only needed oil changes and wiper blades. Driven a full year through all 4 seasons, here's what I think:
Drives smooth. Rear suspension air bags were replaced with springs before I purchased the car, so I do not know how it feels with the air bags. Did not know this at first because the car still rides like a cloud.
Surprisingly powerful for it's weight and 14 year old age. Engine literally purrs whereas I notice other cars with same age/miles sound like they're dying. If I've got the AC or heater blowing on medium low, I cannot hear the engine anymore. Engine ridiculously quiet.
Haters hated initially when I bought this car until they took a ride. People prefer riding in the GM to the 4 bangers. They enjoy the comfortable ride and roominess. Also the premium sound system is a huge plus, I always get asked "Is that stock sounds?" Yes they are! This thing was made for passenger comfort. The back doors have ashtrays! Win! I'm 5'8 and sleep great in this car when I need to at work. Could not sleep in my old Taurus at all. I may get the leather seats replaced with the plush cloth ones since I'm not really a big fan of leather, because it gets hot in the summer and is cold in the winter.
With tinted windows, some aftermarket rims, and some wax, the GM doesn't look so much like your grandpa's car anymore. The woodgrain trim on the interior gives it that extra bit of class. Mine came with an aftermarket sunroof.
I'm a small dude, so the radio and climate controls can be a far reach. Actually have to "get up" to change things. Does not bother me one bit because I love the fact I have so much space around me in the drivers seat. I keep both armrests up so the front seat stays in bench mode because it's super easy to throw all my work luggage in the passenger seat every day rather than lug it over a middle console like my old car. I like being able to move around and not touch anything like my door or a middle console with my arms or legs.
It doesn't handle too much like a boat, but definitely not like a sportscar either. If you purchased this car, you obviously didn't buy it for sporting. Not bad, as I feel very safe driving, but turns kinda wide compared to smaller cars. Has traction control and ABS so no issues driving in rain or snow. Turn traction control off sometimes in snow just for fun!
Depends on who you are. I consider this thing the ultimate driving machine because it suits my driving style perfectly. I'm laid back and relaxed, not sitting up close to the wheel with one white knuckled fist driving and the other fist shaking out the window. This car is not for you!
I like the feeling where I put the car into drive and it feels like "the beast is unleashed" rather than just putting her into gear. Think it has something to do with 2 tons of body-on-frame with a big V8 lurching forward, whatever it is, it's definitely not like anything else I've driven.
I'm really having a hard time thinking of things I do not like about this car. There really isn't much. My next vehicle will surely be a newer G.M. I want to say gas mileage would be the one thing, I average 18-20 mpg during the winter and 21-22 mpg in the summer months. But since I will not give up my V8 power, feel, sound, and the big body style after having experienced it now, I guess I can't complain about the mpg. Oh, car doesn't have an extra power port, just 1 cigarette lighter port. Cup holders can't hold 32 oz energy drink cans. Doors kind of rattle a bit. Wind noise 60+mph. Pedals don't adjust. All very minor things.
The 4.6L V8 200HP package never makes me feel short on power. Jumps off the line pretty nicely and surprises people. And it's nice knowing that even though you're doing 70mph on the freeway, you've got plenty of power to pass up those 70mph-struggling 4-banger buzz-bombs.
Absolutely love this car. Purchased for $2500, 14 years old with 140K miles. Had my 2000 Taurus for 8 years and never had feelings for that car like my G.M. for which I've only had a year. She's my all American Iron, Assembled in Canada!

Fewest repairs of any car I have owned

by inthewoods from Wisconsin | February 24, 2009

I bought my 1998 Grand Marquis in 2000 with 34,000 miles on it. Since then I have put another 120,000 on it and my only expense other than brakes (once) and tires and oil changes was about $500 in front end work. Oh yes, I had to have the cigarette lighter fixed to keep my cell phone charged.
I am now burning about one quart of oil every 2,000 miles. I get as much as 27 mpg on the highway.
I also drive a Toyota Corolla and while the Corolla is equally--but not more, dependable, repairs to the Toyota cost more than for the Grand Marquis. And there is, of course, no comparison to the ride, comfort, noise levels nor roominess. While the gas mileage for my Toyota reaches as much as 37 mpg, the Mercury is always my car of choice when driving more than a few hundred miles. My next car? Another Grand Marquis or Lincoln Town Car.

Roomy Comfort

by FL Chick from Orlando, FL | December 8, 2008

This car is very roomy and comfortable and works well for a larger driver and/or passengers. The drivers seat adjusts to a variety of positions to accommodate all size drivers. I find it easy to maneuver and park, even though it is a very large sedan. The trunk is HUGE!
